TECHNICAL FIELD

The invention relates to cyclopropylamine compounds, in particular the compounds of Formula (I), (II), (III), (IV) or (V), and their use in therapy, including, e.g., in the treatment or prevention of cancer, a neurological disease or condition, or viral infection.

BACKGROUND

Aberrant gene expression in affected tissue as compared to normal tissue is a common characteristic of many human diseases. This is true for cancer and many neurological diseases which are characterized by changes in gene expression patterns. Gene expression patterns are controlled at multiple levels in the cell. Control of gene expression can occur through modifications of DNA: DNA promoter methylation is associated with suppression of gene expression. Several inhibitors of DNA methylation are approved for clinical use including the blockbuster Vidaza™. Another class of modifications involve histones which form the protein scaffold that DNA is normally associated with (coiled around) in eukaryotic cells. Histones play a crucial role in organizing DNA and the regulated coiling and uncoiling of DNA around the histories is critical in controlling gene expression-coiled DNA is typically not accessible for gene transcription. A number of histone modification have been discovered including histone acetylation, histone lysine methylation, histone arginine methylation, histone ubiquinylation, and histone sumoylation, many of which modify accessibility to the associated DNA by the cells transcriptional machinery. These histone marks serve to recruit various protein complexes involved in transcription and repression. An increasing number of studies are painting an intricate picture of how various combinations of histone marks control gene expression in cell-type specific manner and a new term has been coined to capture this concept: the histone code.

The prototypical histone mark is histone acetylation. Histone acetyl transferase and histone deacetylases are the catalytic machines involved in modulation of this histone mark although typically these enzymes are parts of multiprotein complexes containing other proteins involved in reading and modifying histone marks. The components of these protein complexes are typically cell type and typically comprise transcriptional regulators, repressors, co-reppresors, receptors associated with gene expression modulation (e.g., estrogen or androgen receptor). Histone deacetylase inhibitors alter the histone acetylation profile of chromatin. Accordingly, histone deacetylase inhibitors like SAHA, TSA, and many others have been shown to alter gene expression in various in vitro and in viva animal models. Clinically, histone deacetylase inhibitor have demonstrated activity in the cancer setting and are being investigated for oncology indications as well as for neurological conditions and other diseases.

Another modification that is involved in regulating gene expression is histone methylation including lysine and arginine methylation. The methylation status of histone lysines has recently been shown to be important in dynamically regulating gene expression.

A group of enzymes known as histone lysine methyl transferases and histone lysine demethylases are involved in histone lysine modifications. One particular human histone lysine demethylase enzyme called Lysine Specific Demethylase-1 (LSD1) was recently discovered (Shi et al. (2004) Cell 119:941) to be involved in this crucial histone modification. LSD1 has a fair degree of structural similarity, and amino acid identity/homology to polyamine oxidases and monoamine oxidases, all of which (i.e., MAO-A, MAO-B and LSD 1) are flavin dependent amine oxidases which catalyze the oxidation of nitrogen-hydrogen bonds and/or nitrogen carbon bonds.

Several groups have reported LSD1 inhibitors in the literature. Sharma et al. recently reported a new series of urea and thiourea analogs based on an earlier series of polyamines which were shown to inhibit LSD1 and modulate histone methylation and gene expression in cells (J. Med. Chem. 2010 PMID: 20568780). Sharma et al. note that “To date, only a few existing compounds have been shown to inhibit LSD 1.” Some efforts were made to make analogs of the histone peptide that is methylated by the enzyme, other efforts have focused on more small molecule like molecules based on known MAO inhibitors. Gooden et al. reported trans-2-arylcyclopropylamine analogues that inhibit LSD1 with Ki values in the range of 188-566 micromolar (Gooden et al. ((2008) Bioorg. Med. Chem. Let. 1, 8:3047-3051)). Most of these compounds were more potent against MAO-A as compared to MAO-B. Ueda et al. ((2009) J. Am. Chem. Soc. 131(48):17536-17537) reported cyclopropylamine analogs selective for LSD1 over MAO-A and MAO-B that were designed based on reported X-ray crystal structures of these enzymes with a phenylcyclopropylamine-FAD adduct and a FAD-N-propargyl lysine peptide. The reported 1050 value for phenylcyclopropylamine was about 32 micromolar for LSD1 whereas compounds 1 and 2 had values of 2.5 and 1.9 micromolar respectively.

Binda et al. examined a series of phenylcyclopropylamine derivatives in relation to their inhibitory activity against LSD 1 and LSD2 as well as examining stereochemical issues in relation to the cyclopropyl ring (J. Am. Chem. Soc. 2010 May 19; 132(19):6827-33). Binda et al. reported that their para substituted phenylcyclopropylamine derivatives are non-selective which as a group are appear to be better MAO-A inhibitors than MAO-B inhibitors. Furthermore, their inhibitory activities against MAO-A and LSD1 were roughly the same.

Mimasu et al. disclose a series of phenylcyclopropylamine derivatives having benzoyl substitutions at the ortho-position ((2010) Biochemistry PMID: 20568732. Ortho-substituted compounds from this series without a benzoyl group in the ortho-position e.g., phenyl, alkoxy, or having a combination of ortho- and para-substitution appeared to be less potent inhibitors of LSD1 than those compounds having benzoyl substituents in the ortho-position. The most active compounds from this series had a benzoyl group at the ortho-position and one or two meta-fluoro substitutions: biphenyls like S1310 and compounds having large groups in the para-position were less effective LSD1 inhibitors.

The phenylcyclopropylamines have been the subject of many studies designed to elucidate a SAR for MAO inhibition. Kaiser et al. ((1962) J. Med. Chem. 5:1243-1265); Zirkle et al. ((1962) J. Med. Chem. 1265-1284; U.S. Pat. Nos. 3,365,458; 3,471,522; 3,532,749) have disclosed the synthesis and activity of a number of phenylcyclopropylamine related compounds. Other phenylcyclopropylamine type compounds are disclosed in Bolesov et al. ((1974) Zhurnal Organicheskoi Khimii 10:8 1661-1669) and Russian Patent No. 230169 (19681030).

Studies have been conducted with phenylcyclopropylamine related compounds to determine selectivity for MAO-A versus MAO-B since MAO-A inhibitors can cause dangerous side-effects (see e.g., Yoshida et al. (2004) Bioorg. Med. Chem. 12(10):2645-2652; Hruschka et al. (2008) Biorg Med. Chem. (16):7148-7166; Folks et al. (1983) J. Clin. Psychopharmacol. (3)249; and Youdim et al. (1983) Mod. Probl. Pharmacopsychiatry (19):63).

Stereoisomers are typically resolved using chiral HPLC column techniques (e.g., Daicel CHIRALPAK® and CHIRALCEL® columns, Chirex® (utilizing the Pirkle-brush concept), Sumichiral OA® (available from Sumika Chemical Analysis Service, Ltd.), Regis Whelk-0 1® (available from Merck KGaA of Darmstadt, DE), Lux® chiral columns available from Phenomenex, Inc. of Torrance, Calif., US) according to manufacturer's instructions or by outside specialist laboratory (e.g., Syncom BV of Groningen, NL or Chiral Technologies Europe of Illkirch, FR). A gas chromatography-mass spectrometry (“GC-MS”) method may also sometimes be used. Although such techniques typically work to separate a racemate into its respective stereoisomers, sometimes the procedures do not so work, and, for example, the more complicated separate enantioselective synthesis of each of the separate stereoisomers is performed (e.g., by utilizing chiral crystallization techniques) for both pharmacological and toxological testing.

As the ordinary skilled artisan is aware, the absolute configuration of the compounds of the invention can be determined according to standard techniques in the field of chiral compounds. In particular, the isomers of racemic compounds can be isolated by a variety of techniques as described herein and subjected to techniques such as x-ray crystallography, chiral shift reagent, circular dichrosim, chemical derivatization, optical rotation, and/or enantiospecific synthetic techniques to determine the absolute configuration (see e.g., Stephens et al. Chirality. 2008 May 15; 20(5):643-63); Shah et al. Curr Opin Drug Discov Devel. 2001 November; 4(6):764-75 and others.)

In one specific aspect, the invention relates to a composition comprising a compound of Formula (I), (II), (III), (IV) or (V) as described and defined herein, in particular a heterocyclylpropylamine, phenylcyclopropylamine, or pyridinylcyclopropylamine as described herein, or a solvate or pharmaceutically acceptable salt thereof, wherein said compound is the (1S,2R) enantiomer (in respect to the substituents on the cyclopropyl ring) substantially free of the (1R,2S) enantiomer. As used herein “substantially free” means there is an excess of one enantiomer as compared to the other. Preferably “substantially free of (1R,2S) enantiomer” refers to more than 60% (1S,2R) enantiomer and less than 40% (1R,2S) enantiomer. Even more preferably, more than 75% (1S,2R) enantiomer and less than 25% (1R,2S) enantiomer. Even more preferably, more than 90% (1S,2R) enantiomer and less than 10% (1R,2S) enantiomer. Even more preferably, more than 95% (1S,2R) enantiomer and less than 5% (1R,2S) enantiomer. Even more preferably, more than 99% (1S,2R) enantiomer and less than 1% (1R,2S) enantiomer. In calculating the total percent of the composition only the amounts of the 2 enantiomers (i.e., the (1S,2R) enantiomer and the (1R,2S) enantiomer) are used and sum to give 100%.

As used herein, the term “enantiomeric excess” or “ee” or “percent enantiomeric excess” refers to the difference between the mole fraction of one specific enantiomer (i.e., the specified enantiomer) and the mole fraction of the other enantiomer in relation to the sum of the mole fractions of both enantiomers, expressed as a percent value, and thus describes the extent of the excess of one specific enantiomer in relation to the other enantiomer. If, for example, a specific enantiomer is provided in the absence of the other enantiomer, the enantiomeric excess will be 100%, while a racemate comprising equal molar amounts of the two enantiomers will have an enantiomeric excess of 0%. Accordingly, the “enantiomeric excess” or “ee” or “percent enantiomeric excess” is defined by the following formula:

$\frac{\begin{matrix} {\left( {{mole}\mspace{14mu}{fraction}\mspace{14mu}{of}\mspace{14mu}{the}\mspace{14mu}{specified}\mspace{14mu}{enantiomer}} \right) -} \\ \left( {{mole}\mspace{14mu}{fraction}\mspace{14mu}{of}\mspace{14mu}{the}\mspace{14mu}{other}\mspace{14mu}{enantiomer}} \right) \end{matrix}}{\begin{matrix} {\left( {{mole}\mspace{14mu}{fraction}\mspace{14mu}{of}\mspace{14mu}{the}\mspace{14mu}{specified}\mspace{14mu}{enantiomer}} \right) +} \\ \left( {{mole}\mspace{14mu}{fraction}\mspace{14mu}{of}\mspace{14mu}{the}\mspace{14mu}{other}\mspace{14mu}{enantiomer}} \right) \end{matrix}} \cdot 100$

Thus, the invention relates to a composition comprising a compound of Formula (I), (II), (III), (IV) or (V) as described and defined herein, in particular a heterocyclylpropylamine, phenylcyclopropylamine, or pyridinylcyclopropylamine as described herein, or a solvate or pharmaceutically acceptable salt thereof, wherein said composition comprises the (1S,2R) enantiomer (in respect to the substituents on the cyclopropyl ring) of said compound substantially free of the (1R,2S) enantiomer, wherein said compound is chosen from:

Those of skill in the art will further recognize that certain groups may be attached to a parent molecule or may occupy a position in a chain of elements from either end as written. Thus, by way of example only, an unsymmetrical group such as —C(═O)N(R)— may be attached to the parent moiety at either the carbon or the nitrogen.

Asymmetric centers exist in the compounds disclosed herein. These centers are designated by the symbols “R” or “S,” depending on the configuration of substituents around the chiral carbon atom. It should be understood that the invention encompasses all stereochemical isomeric forms, including diastereomeric, enantiomeric, and epimeric forms, as well as d-isomers and I-isomers, and mixtures thereof. Individual stereoisomers of compounds can be prepared synthetically from commercially available starting materials which contain chiral centers or by preparation of mixtures of enantiomeric products followed by separation such as conversion to a mixture of diastereomers followed by separation or recrystallization, chromatographic techniques, direct separation of enantiomers on chiral chromatographic columns, or any other appropriate method known in the art. Starting compounds of particular stereochemistry are either commercially available or can be made and resolved by techniques known in the art. Additionally, the compounds disclosed herein may exist as geometric isomers. The present invention includes all cis, trans, syn, anti, entgegen (E), and zusammen (Z) isomers as well as the appropriate mixtures thereof. Additionally, compounds may exist as tautomers; all tautomeric isomers are provided by this invention. Additionally, the compounds disclosed herein can exist in unsolvated as well as solvated forms with pharmaceutically acceptable solvents such as water, ethanol, and the like. In general, the solvated forms are considered equivalent to the unsolvated forms.

As used herein, the terms “(1S,2R) enantiomer” and “(1R,2S) enantiomer” of a compound according to the invention, in particular of a compound of Formula (I), (II), (III), (IV) or (V), refer to the two possible enantiomers of the trans-isomer (in respect of the substituents on the cyclopropyl ring) of the respective compound. In this connection, the 1-position of the cyclopropyl ring refers to the carbon atom of the cyclopropyl ring which is bound to the terminal amino group of the compound and the 2-position of the cyclopropyl ring refers to the carbon atom which is bound to the adjacent cyclic group (i.e., the cyclic group comprising E, X¹ and X² in Formula (I)) of the compound, unless defined otherwise by the chemical name of any particular compound.

As used herein, the term “preventing an increase in a symptom,” refers to both not allowing a symptom to increase or worsen, as well as reducing the rate of increase in the symptom. For example, a symptom can be measured as the amount of particular disease marker, i.e., a protein (e.g., cancer biomarker). In another example the symptom can be cognitive decline. Preventing an increase, according to the definition provided herein, means that the amount of symptom (e.g., protein or cognitive decline) does not increase or that the rate at which it increases is reduced.

As used herein, the term “treating a disease or disorder,” refers to a slowing of or a reversal of the progress of the disease. Treating a disease or disorder includes treating a symptom and/or reducing the symptoms of the disease.

As used herein, the term “preventing a disease or disorder,” refers to a slowing of the disease or of the onset of the disease or the symptoms thereof. Preventing a disease or disorder can include stopping the onset of the disease or symptoms thereof. As used herein, the term “unit dosage form” refers to a physically discrete unit, such as a capsule or tablet suitable as a unitary dosage for a human patient. Each unit contains a predetermined quantity of a compound of Formula (I), (II), (III), (IV) or (V) which was discovered or believed to produce the desired pharmacokinetic profile which yields the desired therapeutic effect. The dosage unit is composed of a compound of Formula (I), (II), (III), (IV) or (V) in association with at least one pharmaceutically acceptable carrier, salt, excipient, or combination thereof.

As used herein, the term “subject” or “patient” or “individual”, such as the subject in need of treatment or prevention, may be a eukaryote, an animal, a vertebrate animal, a mammal, a rodent (e.g. a guinea pig, a hamster, a rat, a mouse), a murine (e.g. a mouse), a canine (e.g. a dog), a feline (e.g. a cat), an equine (e.g. a horse), a primate, a simian (e.g. a monkey or ape), a monkey (e.g. a marmoset, a baboon), an ape (e.g. gorilla, chimpanzee, orangutang, gibbon), or a human. The meaning of the terms “eukaryote”, “animal”, “mammal”, etc. is well known in the art and can, for example, be deduced from Wehner und Gehring (1995; Thieme Verlag). In the context of this invention, it is particularly envisaged that animals are to be treated which are economically, agronomically or scientifically important. Scientifically important organisms include, but are not limited to, mice, rats, and rabbits. Lower organisms such as, e.g., fruit flies like Drosophila melagonaster and nematodes like Caenorhabditis elegans may also be used in scientific approaches. Non-limiting examples of agronomically important animals are sheep, cattle and pig, while, for example, cats and dogs may be considered as economically important animals. Preferably, the subject/patient/individual is a mammal; more preferably, the subject/patient/individual is a human or a non-human mammal (such as, e.g., a guinea pig, a banister, a rat, a mouse, a rabbit, a dog, a cat, a horse, a monkey, an ape, a marmoset, a baboon, a gorilla, a chimpanzee, an orangutang, a gibbon, a sheep, cattle, or a pig); even more preferably, the subject/patient/individual is a human.

As used herein, the term “dose” or “dosage,” refers the amount of active ingredient that an individual takes or is administered at one time. For example, a 40 mg dose of a compound of Formula (I), (II), (III), (IV) or (V) refers to, in the case of a twice-daily dosage regimen, a situation where the individual takes 40 mg of a compound of Formula (I), (II), (III), (IV) or (V) twice a day, e.g., 40 mg in the morning and 40 mg in the evening. The 40 mg of a compound of Formula (I), (II), (III), (IV) or (V) dose can be divided into two or more dosage units, e.g., two 20 mg dosage units of a compound of Formula (I), (II), (III), (IV) or (V) in tablet form or two 20 mg dosage units of a compound of Formula (I), (II), (III), (IV) or (V) in capsule form.

As used herein, a “pharmaceutically acceptable prodrug” is a compound that may be converted under physiological conditions or by solvolysis to the specified compound or to a pharmaceutically acceptable salt of such compound.

As used herein, a “pharmaceutically active metabolite” is intended to mean a pharmacologically active product produced through metabolism in the body of a specified compound or salt thereof. Metabolites of a compound may be identified using routine techniques known in the art and their activities determined using tests such as those described herein.

As used herein, a “pharmaceutically acceptable salt” is intended to mean a salt that retains the biological effectiveness of the free acids and bases of the specified compound and that is not biologically or otherwise undesirable. A compound for use in the invention may possess a sufficiently acidic, a sufficiently basic, or both functional groups, and accordingly react with any of a number of inorganic or organic bases, and inorganic and organic acids, to form a pharmaceutically acceptable salt. Exemplary pharmaceutically acceptable salts include those salts prepared by reaction of the compounds of the present invention with a mineral or organic acid or an inorganic base, such as salts including sulfates, pyrosulfates, bisulfates, sulfites, bisulfites, phosphates, monohydrophosphates, dihydrophosphates, metaphosphates, pyrophosphates, chlorides, bromides, iodides, acetates, propionates, decanoates, caprylates, acrylates, formates, isobutyrates, caproates, heptanoates, propiolates, oxalates, malonates, succinates, suberates, sebacates, fumarates, maleates, butyne-1,4dioates, hexyne-1,6-dioates, benzoates, chlorobenzoates, methylbenzoates, dinitrobenzoates, hydroxybenzoates, methoxybenzoates, phthalates, sulfonates, xylenesulfonates, phenylacetates, phenylpropionates, phenylbutyrates, citrates, lactates, gamma-hydroxybutyrates, glycollates, tartrates, methane-sulfonates, propanesulfonates, naphthalene-1 sulfonates, naphthalene-2-sulfonates, or mandelates.

As used herein, a “pharmaceutically acceptable carrier” refers to a non-API (API refers to Active Pharmaceutical Ingredient) substances such as disintegrators, binders, fillers, and lubricants used in formulating pharmaceutical products. They are generally safe for administering to humans according to established governmental standards, including those promulgated by the United States Food and Drug Administration and the European Medical Agency.

As is understood by the skilled artisan, certain variables in the list of substituents are repetitive (different name for the same substituent), generic to other terms in the list, and/or partially overlap in content with other terms. In the compounds of the invention, the skilled artisan recognizes that substituents may be attached to the remainder of the molecule via a number of positions and the preferred positions are as illustrated in the Examples.

Additionally, the compound of Formula (I), (II), (III), (IV) or (V) can contain asymmetric carbon atoms and can therefore exist in racemic and optically active forms. Thus, optical isomers or enantiomers, racemates, tautomers, and diastereomers are also encompassed in the compounds of Formula (I), (II), (III), (IV) or (V). The methods of present invention include the use of all such isomers and mixtures thereof. Methods of separation of enantiomeric and diastereomeric mixtures are well known to one skilled in the art. The present invention encompasses any isolated racemic or optically active form of compounds described in Formula (I), (II), (III), (IV) or (V), or any mixture thereof. In one aspect, the compounds of the invention have a trans configuration around the cyclopropyl ring as in trans-phenylcyclopropylamine. In one aspect, the compounds of the invention have a cis configuration around the cyclopropyl ring as in cis-phenylcyclopropylamine. In a preferred aspect, the compounds of Formula (I), (II), (III), (IV) or (V) have the trans configuration.

Typically, compounds according to Formula (I), (II), (III), (IV) or (V) can be effective at an amount of from about 0.01 μg/kg to about 100 mg/kg per day based on total body weight. The active ingredient may be administered at once, or may be divided into a number of smaller doses to be administered at predetermined intervals of time. The suitable dosage unit for each administration can be, e.g., from about 1 μg to about 2000 mg, preferably from about 5 μg to about 1000 mg.

It should be understood that the dosage ranges set forth above are exemplary only and are not intended to limit the scope of this invention. The therapeutically effective amount for each active compound can vary with factors including but not limited to the activity of the compound used, stability of the active compound in the patient's body, the severity of the conditions to be alleviated, the total weight of the patient treated, the route of administration, the ease of absorption, distribution, and excretion of the active compound by the body, the age and sensitivity of the patient to be treated, and the like, as will be apparent to a skilled artisan. The amount of administration can be adjusted as the various factors change over time.

For oral delivery, the active compounds can be incorporated into a formulation that includes pharmaceutically acceptable carriers such as binders (e.g., gelatin, cellulose, gum tragacanth), excipients (e.g., starch, lactose), lubricants (e.g., magnesium stearate, silicon dioxide), disintegrating agents (e.g., alginate, Primogel, and corn starch), and sweetening or flavoring agents (e.g., glucose, sucrose, saccharin, methyl salicylate, and peppermint). The formulation can be orally delivered in the form of enclosed gelatin capsules or compressed tablets. Capsules and tablets can be prepared in any conventional techniques. The capsules and tablets can also be coated with various coatings known in the art to modify the flavors, tastes, colors, and shapes of the capsules and tablets. In addition, liquid carriers such as fatty oil can also be included in capsules.

Suitable oral formulations can also be in the form of suspension, syrup, chewing gum, wafer, elixir, and the like. If desired, conventional agents for modifying flavors, tastes, colors, and shapes of the special forms can also be included. In addition, for convenient administration by enteral feeding tube in patients unable to swallow, the active compounds can be dissolved in an acceptable lipophilic vegetable oil vehicle such as olive oil, corn oil and safflower oil.

The active compounds can also be administered parenterally in the form of solution or suspension, or in lyophilized form capable of conversion into a solution or suspension form before use. In such formulations, diluents or pharmaceutically acceptable carriers such as sterile water and physiological saline buffer can be used. Other conventional solvents, pH buffers, stabilizers, anti-bacteria agents, surfactants, and antioxidants can all be included. For example, useful components include sodium chloride, acetates, citrates or phosphates buffers, glycerin, dextrose, fixed oils, methyl parabens, polyethylene glycol, propylene glycol, sodium bisulfate, benzyl alcohol, ascorbic acid, and the like. The parenteral formulations can be stored in any conventional containers such as vials and ampoules.

Routes of topical administration include nasal, bucal, mucosal, rectal, or vaginal applications. For topical administration, the active compounds can be formulated into lotions, creams, ointments, gels, powders, pastes, sprays, suspensions, drops and aerosols. Thus, one or more thickening agents, humectants, and stabilizing agents can be included in the formulations. Examples of such agents include, but are not limited to, polyethylene glycol, sorbitol, xanthan gum, petrolatum, beeswax, or mineral oil, lanolin, squalene, and the like. A special form of topical administration is delivery by a transdermal patch. Methods for preparing transdermal patches are disclosed, e.g., in Brown, et al. (1988) Ann. Rev. Med. 39:221-229 which is incorporated herein by reference.

Subcutaneous implantation for sustained release of the active compounds may also be a suitable route of administration. This entails surgical procedures for implanting an active compound in any suitable formulation into a subcutaneous space, e.g., beneath the anterior abdominal wall. See, e.g., Wilson et al. (1984) J. Clin. Psych. 45:242-247. Hydrogels can be used as a carrier for the sustained release of the active compounds. Hydrogels are generally known in the art. They are typically made by crosslinking high molecular weight biocompatible polymers into a network, which swells in water to form a gel like material. Preferably, hydrogels are biodegradable or biosorbable. For purposes of this invention, hydrogels made of polyethylene glycols, collagen, or poly(glycolic-co-L-lactic acid) may be useful. See, e.g., Phillips et al. (1984) J. Pharmaceut. Sci., 73: 1718-1720.

The active compounds can also be conjugated, to a water soluble non-immunogenic non-peptidic high molecular weight polymer to form a polymer conjugate. For example, an active compound is covalently linked to polyethylene glycol to form a conjugate. Typically, such a conjugate exhibits improved solubility, stability, and reduced toxicity and immunogenicity. Thus, when administered to a patient, the active compound in the conjugate can have a longer half-life in the body, and exhibit better efficacy. See generally, Burnham (1994) Am. J. Hosp. Pharm. 15:210-218. PEGylated proteins are currently being used in protein replacement therapies and for other therapeutic uses. For example, PEGylated interferon (PEG-INTRON A®) is clinically used for treating Hepatitis B. PEGylated adenosine deaminase (ADAGEN®) is being used to treat severe combined immunodeficiency disease (SCIDS). PEGylated L-asparaginase (ONCAPSPAR®) is being used to treat acute lymphoblastic leukemia (ALL). It is preferred that the covalent linkage between the polymer and the active compound and/or the polymer itself is hydrolytically degradable under physiological conditions. Such conjugates known as “prodrugs” can readily release the active compound inside the body. Controlled release of an active compound can also be achieved by incorporating the active ingredient into microcapsules, nanocapsules, or hydrogels generally known in the art. Other pharmaceutically acceptable prodrugs of the compounds of this invention include, but are not limited to, esters, carbonates, thiocarbonates, N-acyl derivatives, N-acyloxyalkyl derivatives, quaternary derivatives of tertiary amines, N-Mannich bases, Schiff bases, amino acid conjugates, phosphate esters, metal salts and sulfonate esters.

Liposomes can also be used as carriers for the active compounds of the present invention. Liposomes are micelles made of various lipids such as cholesterol, phospholipids, fatty acids, and derivatives thereof. Various modified lipids can also be used. Liposomes can reduce the toxicity of the active compounds, and increase their stability. Methods for preparing liposomal suspensions containing active ingredients therein are generally known in the art. See, e.g., U.S. Pat. No. 4,522,811 ; Prescott, Ed., Methods in Cell Biology, Volume XIV, Academic Press, New York, N.Y. (1976).

The active compounds can also be administered in combination with another active agent that synergistically treats or prevents the same symptoms or is effective for another disease or symptom in the patient treated so long as the other active agent does not interfere with or adversely affect the effects of the active compounds of this invention. Such other active agents include but are not limited to anti-inflammation agents, antiviral agents, antibiotics, antifungal agents, antithrombotic agents, cardiovascular drugs, cholesterol lowering agents, anti-cancer drugs, hypertension drugs, and the like.

Examples of antineoplastic agents that can be used in combination with the compounds and methods of the present invention include, in general, and as appropriate, alkylating agents, anti-metabolites, epidophyllotoxins, antineoplastic enzymes, topoisomerase inhibitors, procarbazines, mitoxantrones, platinum coordination complexes, biological response modifiers and growth inhibitors, hormonal/anti-hormonal therapeutic agents and haematopoietic growth factors. Exemplary classes of antineoplastic include the anthracyclines, vinca drugs, mitomycins, bleomycins, cytotoxic nucleosides, epothilones, discodermolides, pteridines, diynenes and podophyllotoxins. Particularly useful members of those classes include, for example, caminomycin, daunorubicin, aminopterin, methotrexate, methopterin, dichloromethotrexate, mitomycin C, porfiromycin, 5-fluorouracil, 6-mercaptopurine, gemcitabine, cytosine arabinoside, podophyllotoxin or podo-phyllotoxin derivatives such as etoposide, etoposide phosphate or teniposide, melphalan, vinblastine, vincristine, leurosidine, vindesine, leurosine, paclitaxel and the like. Other useful antineoplastic agents include estramustine, carboplatin, cyclophosphamide, bleomycin, gemcitibine, ifosamide, melphalan, hexamethyl melamine, thiotepa, cytarabin, idatrexate, trimetrexate, dacarbazine, L-asparaginase, camptothecin, CPT-11, topotecan, ara-C, bicalutamide, flutamide, leuprolide, pyridobenzoindole derivatives, interferons and interleukins.

EXAMPLES

The program used to generate the names corresponding to the structures in the Example compounds below was ChemBioDraw Ultra 11.0.1. This program named the molecules as the (1S,2R) configuration due to the configuration of the input structure and the “trans” term has been substituted in the place of the (1S,2R) term specified by the program. The structures depicted below for the Example compounds below are shown as having one particular stereochemical configuration around the cyclopropyl carbon atoms of the phenylcyclopropylamine core (1S,2R). All the compounds synthesized in the Examples are mixtures having both configurations (1R,2S) and (1S,2R), that is to say they are “trans” in respect to the cyclopropyl ring of the cyclopropyl ring system. This is due to the fact the cyclopropyl derivatives used as starting material are “trans”. It is contemplated that the cis configuration starting material or the individual diastereomers could be used as starting material, all of which are either commercially or synthetically available. Thus, the invention relates to compounds of Formula (I), (II), (III), (IV) or (V) and those of the examples that have specific stereochemical configurations around the cyclopropyl ring e.g., trans ((1R,2S) and (1S,2R)) and cis ((1R,2R) and (1S,2S)). A preferred stereochemical configuration around the cyclopropyl ring is trans.

The compounds of the examples can also be synthesized or provided in a salt form. The skilled artisan is aware and capable of making salt forms and/or converting salt forms of the compounds of the invention, e.g., compounds of Formula (I), (II), (III), (IV) or (V) and those of the Examples. In some cases the compounds of Formula (I), (II), (III), (IV) or (V) and the Examples can be more stable as salt forms as compared to free base.

In reference to the synthetic schemes described herein the following intermediates (and analogous intermediates or derivatives thereof) can be made using the following procedures.

Intermediate A: (E)-ethyl 3-(4-bromophenyl)acrylate

A solution of triethyl phosphonoacetate (13.1 g, 0.0589 mol) was added slowly (dropwise) to a solution of Potassium-tert-butoxide (6.59 g, 0.0589 mol), in dry THF (150 mL) at −5° C., stirred for 30-45 mins at the same temperature, then a solution of 4-Bromo benzaldehyde (10 g, 0.054 mol), in dry THF (50 mL) was slowly added dropwise at −5° C. over a period of 15 mins, stirred the reaction mixture for 30 mins at the same temperature. After completion of reaction by TLC, the reaction mixture was poured into ice water (300 mL), extracted with EtOAc (2×200 mL). The combined organic extracts were washed with sat NaHCO₃ solution (200 mL), water (200 mL), brine (200 mL) and dried over anhydrous Na₂SO₄, filtered and evaporated to get crude (E)-ethyl 3-(4-bromophenyl)acrylate (10 g, 72%) as pale green liquid. This is carried to next step without further purification.

Intermediate B: (Trans)-ethyl 2-(4-bromophenyl)cyclopropanecarboxylate

Trimethyl sulfoxonium iodide (5.19 g, 0.0236 mol) was added slowly in small portions over a period of 20 min. to a suspension of sodium hydride (0.44 g, 0.0236 mol) in dry DMSO (80 mL) at rt, stirred for 1 h, till the formation of clear solution.

Example 63 Enantiomers of 4′-((trans)-2-aminocyclopropyl)biphenyl-3-ol hydrochloride

Each of these compounds corresponds to each of the possible trans-isomers [(1R,2S) and (1S,2R)] of the product described in Example 4. The synthetic procedure used for their synthesis was similar to the one described in Example 4. Chiral HPLC resolution of the diastereomeric mixture was performed at the N-Boc stage, followed by final carbamate deprotection of each of these two enantiomers.

The conditions used to perform this chiral separation are:

Separation by chiral preparative HPLC: Every injection is prepared from 40 mg of the racemic mixture dissolved in a mixture of EtOH, Hexane, THF and diethylamine. These injections were separated on a Chiral Pak-IC (250×30 mm ID) 5 μm at ambient temperature eluting with 0.2% DEA in 93/7 hexane/EtOH at 35 mL/min. The solutions from the chiral separation were concentrated in vacuum to afford the resolved enantiomers.

Analytical determination of enantiomeric excess (ee): ChiralCel OD-H 250×4.6 mm ID, 5 μm, 0.1% TEA in 75/25 hexane/EtOH at 1 mL/min at ambient temperature, with UV analysis at 260 nm. Enantiomers eluted at 4.93 and 7.90 min, each with >98% enantiomeric excess.

Analytical purity: Acquity UPLC BEH C18 100×2.1 mm ID, 1.7 μm, 0.025% TEA in a gradient H2O:ACN (T/%/B, 0/10, 4/80, 6/80, 6.1/10) at 0.3 mL/min at ambient temperature, with UV analysis at 259 nm. Elution at 2.40 min, each with >99.5% purity. Without being bound by theory, it is believed that mixtures, e.g., racemates corresponding to a compound of Formula (I), (II), (III), (IV) or (V) can be resolved in the individual enantiomers or an enantiomer substantially free of the other enantiomer. Thus, the skilled artisan, in view of the disclosure described herein can isolate or purify enantiomers from racemates or mixtures of enantiomers in view of the disclosure herein utilizing standard organic chemistry techniques for separating enantiomers.

Example 125 Biological Assays

The compounds of the invention can be tested for their ability to inhibit LSD 1. The ability of the compounds of the invention to inhibit LSD 1 can be tested as follows. Human recombinant LSD1 protein was purchased from BPS Bioscience Inc. In order to monitor LSD1 enzymatic activity and/or its inhibition rate by our inhibitor(s) of interest, di-methylated H3-K4 peptide (Millipore) was chosen as a substrate. The demethylase activity was estimated, under aerobic conditions, by measuring the release of H₂O₂ produced during the catalytic process, using the Amplex® Red peroxide/peroxidase-coupled assay kit (Invitrogen).

Briefly, a fixed amount of LSD1 was incubated on ice for 15 minutes, in the absence and/or in the presence of various concentrations of inhibitor (e.g., from 0 to 75 μM, depending on the inhibitor strength). Tranylcypromine (Biomol International) was used as a control for inhibition. Within the experiment, each concentration of inhibitor was tested in triplicate. After leaving the enzyme interacting with the inhibitor, 12.5 μM of di-methylated H3-K4 peptide was added to each reaction and the experiment was left for 1 hour at 37° C. in the dark. The enzymatic reactions were set up in a 50 mM sodium phosphate, pH 7.4 buffer. At the end of the incubation, Amplex® Red reagent and horseradish peroxidase (HPR) solution were added to the reaction according to the recommendations provided by the supplier (Invitrogen), and left to incubate for 30 extra minutes at room temperature in the dark. A 1 μM H₂O₂ solution was used as a control of the kit efficiency. The conversion of the Amplex® Red reagent to resorufin due to the presence of H₂O₂ in the assay, was monitored by fluorescence (excitation at 540 nm, emission at 590 nm) using a microplate reader (Infinite 200, Tecan). Arbitrary units were used to measure level of H₂O₂ produced in the absence and/or in the presence of inhibitor.

The maximum demethylase activity of LSD 1 was obtained in the absence of inhibitor and corrected for background fluorescence in the absence of LSD1. The Ki (1050) of each inhibitor was estimated at half of the maximum activity.

The results presented in Table 1 below show the results of the LSD1 inhibition studies for a number of the Example compounds. Parnate (2-trans phenylcyclopropylamine) was found to have a Ki (IC50) of from about 15 to 35 micromolar depending on the enzyme preparation. The studies show that the compounds of the invention have unexpectedly potent LSD 1 inhibition.

Example 126 Biological Assays—Monoamine Oxidase Assays for Determining the Selectivity of the Compounds of the Invention for LSD1

Human recombinant monoamine oxidase proteins MAO-A and MAO-B were purchased from Sigma Aldrich. MAOs catalyze the oxidative deamination of primary, secondary and tertiary amines. In order to monitor MAO enzymatic activities and/or their inhibition rate by inhibitor(s) of interest, a fluorescent-based (inhibitor)-screening assay was set up. 3-(2-Aminophenyl)-3-oxopropanamine (kynuramine dihydrobromide, Sigma Aldrich), a non fluorescent compound was chosen as a substrate. Kynuranrine is a non-specific substrate for both MAOs activities. While undergoing oxidative deamination by MAO activities, kynuramine is converted into 4-hydroxyquinoline (4-HQ), a resulting fluorescent product.

The monoamine oxidase activity was estimated by measuring the conversion of kynuramine into 4-hydroxyquinoline. Assays were conducted in 96-well black plates with clear bottom (Corning) in a final volume of 100 μL. The assay buffer was 100 mM HEPES, pH 7.5. Each experiment was performed in triplicate within the same experiment.

Briefly, a fixed amount of MAO (0.25 μg for MAO-A and 0.5 μg for MAO-B) was incubated on ice for 15 minutes in the reaction buffer, in the absence and/or in the presence of various concentrations of inhibitor (e.g., from 0 to 50 μM, depending on the inhibitor strength). Tranylcypromine (Biomol International) was used as a control for inhibition.

After leaving the enzyme(s) interacting with the inhibitor, 60 to 90 μM of kynuramine was added to each reaction for MAO-B and MAO-A assay respectively, and the reaction was left for 1 hour at 37° C. in the dark. The oxidative deamination of the substrate was stopped by adding 50 μL (v/v) of NaOH 2N. The conversion of kynuramine to 4-hydroxyquinoline, was monitored by fluorescence (excitation at 320 nm, emission at 360 nm) using a microplate reader (Infinite 200, Tecan). Arbitrary units were used to measure levels of fluorescence produced in the absence and/or in the presence of inhibitor.

The maximum of oxidative deamination activity was obtained by measuring the amount of 4-hydroxyquinoline formed from kynuramine deamination in the absence of inhibitor and corrected for background fluorescence in the absence of MAO enzymes. The Ki (IC50) of each inhibitor was determined at Vmax/2.

The ranges for the Ki value reported in Table 1 are for MAO-A, MAO-B and LSD 1—I=between 1 μM and 40 μM; II=between 0.1 μM and 1 μM; III between 0.001 μM and 0.1 μM. “nd” means “not determined”.

Generally compounds of Examples were found to have Ki (IC50) values for MAO-A and MAO-B greater than the LSD1 Ki values, whereas LSD1 Ki values were generally lower than 0.5 μM.

Thus the compounds of the invention are unexpectedly potent LSD1 inhibitors and unexpectedly selective for LSD1 as compared to MAO-A and MAO-B, or the compounds are dual inhibitors of LSD1 and MAO-B.

Some compounds of the Examples have been tested for antiproliferative/cytotoxic activity and been found to have activity in the micromolar to low micromolar range against cancer cell lines including HCT-116.

Previous reports of LSD1 have found that it is involved in cell proliferation and growth. Some studies have implicated LSD1 as a therapeutic target for cancer. Huang et al. (2007) PNAS 104:8023-8028 found that polyamine inhibitors of LSD1 modestly cause the reexpression of genes aberrantly silenced in cancer cells and particularly colorectal cancer (Huang et al. Clin Cancer Res. (2009) Dec. 1; 15(23):7217-28. Epub 2009 Nov. 24. PMID: 19934284). Scoumanne et al. ((2007) J. Biol. Chem. May 25; 282(21):15471-5) found that deficiency in LSD1 leads to a partial cell cycle arrest in G2/M and sensitizes cells to growth suppression induced by DNA damage. Kahl et al. ((2006) Cancer Res. 66(23):11341-7.) found that LSD1 expression is correlated with prostate cancer aggressiveness. Metzger et al. reported that LSD 1 modulation by siRNA and pargyline regulates androgen receptor (AR) and may have therapeutic potential in cancers where AR plays a role, like prostate, testis, and brain cancers. Lee et al. ((2006) Chem. Biol. 13:563-567) reported that tranylcypromine derepresses Egr-1 gene expression in some cancer lines. A body of evidence is accumulating that Egr-1 is a tumor suppressor gene in many contexts (see e.g., Calogero et al. (2004) Cancer Cell International 4:1 exogenous expression of EGR-1 resulted in growth arrest and eventual cell death in primary cancer cell lines; Lucerna et al. (2006) Cancer Research 66, 6708-6713 show that sustained expression of Egr-1 causes antiangiogeneic effects and inhibits tumor growth in some models; Ferraro et al. ((2005) J. Clin. Oncol. March 20; 23(9):1921-6) reported that Egr-1 is downregulated in lung cancer patients with a higher risk of recurrence and may be more resistant to therapy. Thus, increasing Egr-1 expression via inhibition of LSD1 is a therapeutic approach for some cancers. Recent studies have also implicated. LSD1 in brain cancer (Schulte et al. (2009) Cancer Res. March 1; 69(5):2065-71). Other studies have implicated LSD1 in breast cancer (Liras et al. Carcinogenesis. PMID: 20042638).

Thus, a body of evidence has implicated LSD 1 in a number of cancers, which suggests that LSD1 is a therapeutic target for cancer. The instant inventors have discovered a class of LSD1 inhibitors that can be used to treat diseases where LSD1 is implicated as a therapeutic target like cancer. Accordingly, the phenylcyclopropylamine compounds of the invention can be used to treat such diseases.

Recent studies have also implicated LSD1 in viral infection and reactivation. In particular it was shown that pharmacological inhibitors of LSD1 like parnate and siRNA knock down of LSD 1 caused reduced viral infectivity and reduced reactivation after latency (Liang et al. (2009) Nat. Med. 15:1312-1317). Therefore it is believed that the compounds of the invention can be used for treating or preventing viral infection. Furthermore, it is believed that the compounds of the invention can treat or prevent viral reactivation after latency.

Thus, without wishing to be bound by theory, the inventors have identified a new class of substituted heterocyclylpropylamines, phenylcyclopropylamines, and pyridinylcyclopropanamine containing LSD I inhibitors with unexpected potency and selectivity for LSD1 a biologically relevant target in oncology and other diseases and/or LSD1/MAO-B.
